Context refers to the physical and social situation in
which a service-based application or
a service is embedded. It is defined by any information that can be
used to characterize the situation of an entity - be it a person, a
place or a physical or computational object - this is because of the
way this information is used in interpretation rather than because of
its intrinsic
properties.[CD-IA-1.1.1][CD-JRA-1.1.5][PO-JRA-1.1.3]

The circumstances that form
the setting for an event, statement, or idea, and in terms of which it
can be fully understood. [Oxford Dict.]
